What causes excessive sweating?

This condition can result from intense heat or physical exercise. However, when a person sweats excessively on the head, forehead, chest, or back for no apparent reason, they are likely dealing with hyperhidrosis.

Is sweating a lot in these areas of the body healthy?

Sweating can be uncomfortable, but it's the body's way of balancing its temperature. However, if you sweat excessively, even when unnecessary, it's considered excessive sweating, and there are appropriate treatments for this, such as non-surgical injections.

Can excessive sweating be a sign of vascular problems?

Sweating profusely when not exercising, in a hot environment, or with a fever can be a symptom of vascular problems. This is especially true if you also experience symptoms of dizziness, shortness of breath, nausea, or chest pain. Consult a vascular specialist for a medical diagnosis.

What is Hyperhidrosis?

Hyperhidrosis is characterized by abnormally excessive sweating, even under normal conditions without physical exercise or associated high temperatures, caused by the sympathetic nervous system.

This condition may be generalized, or occur with greater incidence in armpits, in the hands and feet, or in other parts of the body such as:

Scalp
Forehead
Chest
Back

Excessive sweating ends up interfering with patients' daily activities and, in more severe cases, causing social embarrassment.

This condition is more common than you might think. In Portugal, it's estimated that at least 500,000 people suffer from hyperhidrosis in various areas of the body.

Causes

The causes of excessive sweating can be linked to hereditary, emotional, or other pathological factors.

Primary Hyperhidrosis

This type of hyperhidrosis appears in childhood or adolescence in specific areas such as the scalp, forehead, hands, feet, or others.

Since it is impossible to determine the factor that triggers this condition, it is believed to be a hereditary characteristic.

Secondary Hyperhidrosis

We are talking about a condition of excessive sweating that generally appears in adulthood and is caused by an illness or side effect of medication.

In this case, sweating is widespread throughout the body and also occurs during sleep.

Excessive Sweating in Various Areas of the Body

When hyperhidrosis occurs in areas such as the head, forehead, chest or back, the most effective treatment is a non-surgical option based on injections.

It is a safe treatment, with no side effects, and is practically painless, performed with a very fine needle.

Although effective, this procedure only temporarily reduces excessive sweating, as the injected substance is naturally absorbed by the body. To maintain its effect, it should be administered every 3–6 months, on average.
